Both the US and Israel believe Iran has the technical capacity to build one nuclear bomb within a year if it decides to do so, but both countries also believe the chances that Teheran will indeed make that decision are slim, according to assessments made known to The Jerusalem Post. According to these Israeli assessments, there is not much difference now between the US and Israel regarding a timeline for a "worst case scenario" on Iran’s development of a bomb. At the same time, both Jerusalem and Washington currently believe that "worst case scenario is not likely to materialize."
